Definitions

  • the present invention relates to geothermal power plants. More specifically, the invention relates to a geothermal power plant providing technical and commercial advantages over state of the art geothermal power plants, particularly when geothermal drill holes are situated over a large area.
  • Geothermal power is energy generated from heat stored in the earth, or the collection of absorbed heat derived from underground.
  • Most common types of geothermal power plants are flash and then binary cycle plants.
  • Binary cycle power plants pass moderately hot geothermal water by a secondary fluid with a much lower boiling point than water, which secondary fluid thereby evaporates and drives turbines.
  • Flash type is the most common where the high temperature steam is taken directly from bore well and fed to the turbine which drives the generator.
  • Enhanced Geothermal Systems (EGS) is a new alternative geothermal technology. EGS typically uses deep that wells into hot rock in order to inject water and use returning steam to generate power.
  • start of payback is late and the redundancy and versatility with respect to load balancing is limited. More specifically, the design to operation period is typical 6-10 years, start of payback is typically from year 7-9 and the redundancy is limited in case of well reduced power output. Further, engineering is borious and expensive because every plant is tailor made, which is complex and expensive. Furthermore well bores must be near the centralized power plant in order to avoid excessive pressure losses and condensing of steam in the pipes. Also, the impact on the environment is negative with large power structures and unsightly piping.
  • the present invention provides a geothermal power plant, distinguished in that it comprises units that are modularized and adapted in order to fit into one container or more containers, as geothermal container units,
  • the geothermal container units are dimensioned in order to be adapted to extract geothermal energy from one drill bore or that of an average hole, and
  • each geothermal container unit has means for being electrically connected to other geothermal container units as well as electric power network, thereby providing a geothermal power plant arranged in a network providing load balancing and redundancy.
  • the geothermal power plant can be either flash or binary cycle.
  • the invention is a flash/binary cycle geothermal power plant comprising,
  • said units are modularized and adapted in order to fit into one or more standard containers, as a geothermal container unit,
  • the geothermal container units are dimensioned in order to be adapted to extract geothermal energy from mainly one borehole
  • each geothermal container unit has means for being electrically connected to other geothermal container units as well as electric power network, thereby providing a geothermal power plant arranged in a network providing load balancing and redundancy.
  • each modular and containerized unit is placed next to or in close vicinity of a respective borehole platform (wellbore, drill bore, drill hole), avoiding transport of steam and resulting pressure losses and environmental disadvantages.
  • the electrical cables for interconnecting the geothermal containerized units are buried in order to reduce the environmental impact.
  • a typical containerized unit is preferably dimensioned to be arranged for 5 MW installed capacity, however, fully adaptable to the capacity obtainable from the local well bores, one or more.
  • the geothermal power plant is arranged in a peer-to-peer network providing remote monitoring and control.
  • the remote management tools centralize control and maximize plant productivity. This comprises preventive maintenance sensors and software in order to reduce risk of failure.
  • Preferably all units comprise additional turbine rotor with blades, which onsite easily can be used to replace damaged turbine rotors.
  • the decentralized network provides complete redundancy against failure.
  • the deliverable will be electrical power from about 5 MW up to 50 MW or above, collecting geothermal energy from a much larger area than the traditional area that is within a radius of ca. 2 km from a central power plant.
  • the modular design enables the power plant to be highly scalable, and adaptable to local demand.
  • FIG. 1 illustrates the components of a single geothermal container unit
  • FIG. 2 illustrates the several geothermal units comprising a geothermal power system
  • FIG. 3 a illustrates a the plan for a conventional geothermal power plant
  • FIG. 3 b illustrates the plan for a state of the art geothermal power system according to the invention
  • FIG. 4 illustrates 6 years earlier start up time of a typical geothermal power project compared to a state of the art geothermal power system according to the invention
  • FIG. 5 illustrates the earlier payback of a state of the art geothermal power system according to the invention compared to a conventional geothermal power plant
  • FIG. 1 illustrating a geothermal power system according to the present invention, more specifically a geothermal container unit according to the present invention. More specifically, FIG. 1 illustrates the contents of a flash/binary cycle geothermal container units comprising of a steam processing unit 1 (comprises steam and moisture separator for the flash type systems and evaporator for binary type systems), which is operatively coupled to a turbine/generator unit 2 , a condensing unit 3 and a cooling tower 4 .
  • a steam processing unit 1 comprising steam and moisture separator for the flash type systems and evaporator for binary type systems
  • Every part of the geothermal power plant of the invention can comprise of prior art technology, but the assembly thereof is providing a surprising technical and economical beneficial effect.
  • new and improved technology is preferably used or replacing older technology as the technology develops further.
  • FIG. 2 is a plan illustrating in further detail how the geothermal power system of the present invention is assembled from several containerized units
  • FIG. 3 a illustrates the current geothermal power plant technology, illustrating the centralized power plant and how it is connected to surrounding bore holes each being no further away than 2 km, the connection compriseing of on-surface steam pipes.
  • FIG. 3 b illustrates the plan for a state of the art geothermal power system according to the invention, illustrating the network of geothermal container units distributed on larger area.
  • FIG. 4 illustrates the timeline for conventional geothermal power plant project and the same for the geothermal power system of the present invention displaying up to 6 years earlier to operation and income.
  • FIG. 5 illustrates the amount of earlier acquired income according to the invention (area between 1 and 2) compared to that of a conventional geothermal plant.
